progress property

double progress

The progress from the arrow's tail starting point, as a ratio of its total length clamped to the range [0, 1]. Gets the progress of the arrow tail, 0 by default.

Implementation

double get progress;
void progress=(double value)

The progress from the arrow's tail starting point, as a ratio of its total length clamped to the range [0, 1]. Sets the progress of the arrow tail from its starting point as a ratio of its total length clamped to the range [0; 1].

As the progress varies, the equivalent part of the arrow tail gets covered by the progress color. The rest of the arrow tail until its end point, including the head, retains the line color.

Implementation

set progress(double value);
